' Renewed May 23, 1933 The present invention relates to the production of coloring preparations and their application. We have found that valuable coloring preparations are obtained by incorporating the internal others known as morpholines (obtained by splitting oil water from hydroxy-alkylamines) and corresponding to the'general formula;

onroni '5 '8 g 1 in which R is hydrogen or an alkyl, aryl or cycloalkyl radicle which may also contain a substituent, as for example a hydroxyl or amino group, and one or more hydrogen atoms of the nucleus may be replaced by alkyl groups, with coloring materials or preparations containing the same. Ethers of the aforesaid nature are for example Ii-methyl, 2.6-dimethyl or N-e-hydroxy-ethyl morpholines, N-phenyl morpholine or N-cyclohexyl morpholine and the like. The said others may be employed asv such or in the form of their salts with inorganic or organic acids such as hydrochloric, sulphuric, formic or acetic acids or the acids of animal or vegetable fats or oils and the like. The amount of the others employed will usually vary between 1 and 500 percent,

preferably between and 500 percent by weight of the coloring sitter.

The employment of the said bases or their salts for the production of printing pastes or dyebaths 35 is advantageous because the presence of the bases or their salts promotes the equalization'and thorough dyeing and prints and dyeings are obtained therewith which are usually distinguished by clarity and depth. Furthermore, the bases and 49 their salts have a good dispersing power for dyestufls, so that it is especially suitable to employ them for the preparation of high quality dyest powders and pastes in which the coloring terials are very finely dispersed andremain in this state on dissolving or diluting the preparations. 1i desired, the said preparations may cont organic diluents such asglycerol and/or 3 agents such as are employed for vetting 0 .1 such as glucose or iodehyde sulphoiwlates. v

The following examples will further illustrate the nature of this invention. but the invention is not restricted to these pies. The-parts we are by weight. a

Example 1 1 cubic centimetreof morpholine is added to each litre of a dyebath for 100 kilograms of woolen piece goods containing in 3 cubic metres of water 100 grams of wool fast yellow (Schultz, Farbstofitabellen 1923, No. 23), 25 grams of anthraquinone blue SR, Extra (Schultz, Farbstofftabellen 1923, No. 861) 200 grams of supramine red B (Schultz, Farbstofitabellen 1923, Vol. 2, page 104), 10 kilograms of Glaubers salt and 4 kilograms of a 98 per cent sulphuric acid. The goods are introduced into the dyebath at about 60 C. and are finished off in the usual manner.

In thismanner level dyeings free from objection are obtained without diificulty with a combination of dyestuffs which under ordinary conditions are badly levelling and unsuitable for the preparation of mixed shades.

Example 2 g A dyebath of 1 cubic metre for 100 kilograms of woollen hat bodies is charged with 8 kilograms of naphthyle black 103 (Schultz, Farbstofltabellen 1923, No. 217) 10 kilograms of Glaubers 8 salt. 5 kilograms of acetic acid and 3 kilo of N-u-hydroxyethyl morpholine,

ment. Well and thoroughly dyed wool waste is 9 obtained in a much shorter time'than would 'otherwise be the case, even with material which is thoroughly dyed only with dificulty. By the of the dyeing process, a protection against injury to the fibres is obtained.

Example 3 A paste of '10s gr of indanthrene violet R Extra Paste (Schultz, Farbstofitabellen 1923, No. 766), together with we grams of hydrosulphite, 20o gr oi N-phenyl morpholine (obtainable by the action of aniline on dichlorethyl ether),

gr of po and 800 grams of starchtish thickening, is printed ontocotton c the prints are for e utes in a Mather Platt apparatus, rinsed, soaped and finished off. Beautiful, clear, deep prints areobtained.

Example 4 A 100 parts of indanthrene blue RS Paste (Schultz, Farbstofitabellen 1923, No. 838) are -mixed with 1 part of the internal ether C Fla-CH1 CoHuN GHQ-CH:

- being stable to frost.

Instead of N-cyclohexylmorpholine the same amount of 2.6-dimethylmorpholine may be used.

What we claim is:--

1. As a new composition a coloring preparation. comprising an organic coloring material and a morpholine.

2. As a new composition a coloring preparation comprising a water-insoluble organic coloring material and a morpholine.

3. As a new composition a coloring preparation comprising a vat clyestufi and a morpholine.

4. As a new composition a coloring preparation comprising a vat dyestufi, a morpholine and a reducing agent capable of reducing vat dyestufls.

5. As a new composition a coloring preparation comprising an organic coloring material and morpholine.

6. As a new composition a coloring preparation I comprising an organic coloring material and N- hydroxyethyl-morpholine.

7. As a new composition a coloring preparation comprising an organic coloring material and N- cyclohexyl-morpholine.

.8. As a new composition a dyebath comprising between and 500 per cent, by weight of the dyestufi, of a morpholine.

9. As a new composition a dyestuff paste comprising from about to 200 per cent, by weight of the dyestufi, of a morpholine.

10. As a new composition a vat dyestufi paste comprising about 200 per cent, by weightof thev dyestuif, of a. morpholine and a. reducing agent for said vat dyestufi.
